High Sensitivity: Capable of detecting very low concentrations of toxins. Specificity: High specificity due to the use of antibodies or receptors. Quantitative: Provides quantitative measurements of target molecules. Versatility: Applicable to a wide range of substances and sample types.
Limitations:
Complexity: Some assays, like RIA, require specialized equipment and handling procedures. Interference: Potential for interference from other substances in the sample, leading to false results. Cost: High cost of reagents and equipment for certain types of assays.
